The Use of Non-Cognitives and Learning Strategies as a Predictor for Completion of Developmental Mathematics at a Community College

With a large global, national, state, and local drive for post-secondary credentials, higher education institutes are exploring new retention and graduation strategies to meet the needs of the employers and employees. Many students who are unprepared for college level work will enter a community college to take developmental courses. Developmental mathematics has been a large barrier to completion and success in community college. The purpose of this study was to explore the ability of non-cognitive traits to predict persistence in completion of a developmental math sequence at a community college. Non-cognitive traits were identified from the three components of strategic learning found in the Learning and Study Strategy Inventory (LASSI): (a) the skill component (information processing, selecting main ideas and test strategies), b) the will of the student component (attitude, motivation and anxiety), and (c) the self-regulation component (concentration, time management, self-testing and study aids). A logistical regression showed the strength of correlation to predict the success of students at a community college. Such factors that were significant in predicting success were age, Pell Grant status, three individual LASSI questions, motivation subscale, testing strategies subscale, and when combined testing and concentration. Even though weak as individual predictors, the use of multiple variables strengthens the prediction. With an open door policy, colleges need to identify students that are in danger of attrition and provide additional support that will increase the likelihood of their success. Along with prior academic background and demographics, non-cognitive variables and learning strategies can only strengthen predictability of risk of student attrition. With this knowledge, proper and timely intervention strategies can be used to support student success. This research challenges community colleges to target all problem areas in its approach to identify high risk students

A Look at Tuberculosis and Multi-Drug Resistant TB in the United States & China

There are many things plaguing the world today, one of them is Mycobacterium tuberculosis otherwise known as Tuberculosis (TB). Since it’s origin TB has become more virulent against antibiotics and became multi-drug resistant (MDR-TB). Two countries come to mind for comparison, China and the United States. China is having severe problems with the disease while the United States is managing it a bit better. Each country has unique circumstances and the statistics show that both may be doing better with just TB but MDR-TB is sticking around and gradually becoming more and more of an issue.https://scholarscompass.vcu.edu/uresposters/1067/thumbnail.jp

Engaging the Adult Learner in Studio Violin Lessons

Music has an important role in nearly every adult life. For most, their participation in music involves listening to recordings, attending concerts, or driving their children to music lessons and rehearsals. Many adults are hesitant to approach learning an instrument because they are aware that the majority of musical learning materials and methods are geared towards children. However, research suggests that there is no reason that adults cannot be as successful at playing an instrument as children. In fact, in many ways, adults are positioned to be more successful musicians, due to their life experiences, self-motivation, and self-concept for learning. Teaching adults can not only be emotionally rewarding, it also presents a market for the enterprising studio teacher, if the instructor is aware of the several unique aspects of teaching adult beginners which I will introduce in this document. I will discuss adult learning concepts, including lifelong learning and andragogy. Along with introducing concepts and relevant research, I will incorporate examples from my experiences teaching violin to adult learners. Additionally, I will explore why adults are motivated to learn to play instruments, as well as the possible benefits of learning a musical instrument. Furthermore, working with adult students offers benefits to the private instructor. However, teaching adults can present challenges to the studio teacher, who must be flexible and adopt the role of facilitator. Use of various studio strategies may aid the instructor in creating a productive learning environment. Oftentimes, adults are interested in the social opportunities that ensemble playing provides, but are not ready to play in front of others initially. I will explore how studio teachers can create a community and studio culture in order to fulfill adult students’ desire for social interaction. In addition, I discuss the physical, cognitive, and emotional challenges that adults can present, as well as strategies for accommodating these challenges and a variety of learning styles. Finally, I will present a suggested progression for adult violin learning during the first year of instruction

Single particle characterization using the soot particle aerosol mass spectrometer (SP-AMS)

Understanding the impact of atmospheric black carbon (BC) containing particles on human health and radiative forcing requires knowledge of the mixing state of BC, including the characteristics of the materials with which it is internally mixed. In this study, we demonstrate for the first time the capabilities of the Aerodyne Soot-Particle Aerosol Mass Spectrometer equipped with a light scattering module (LS-SP-AMS) to examine the mixing state of refractory BC (rBC) and other aerosol components in an urban environment (downtown Toronto). K-means clustering analysis was used to classify single particle mass spectra into chemically distinct groups. One resultant cluster is dominated by rBC mass spectral signals (C+1 to C+5) while the organic signals fall into a few major clusters, identified as hydrocarbon-like organic aerosol (HOA), oxygenated organic aerosol (OOA), and cooking emission organic aerosol (COA). A nearly external mixing is observed with small BC particles only thinly coated by HOA ( 28% by mass on average), while over 90% of the HOA-rich particles did not contain detectable amounts of rBC. Most of the particles classified into other inorganic and organic clusters were not significantly associated with BC. The single particle results also suggest that HOA and COA emitted from anthropogenic sources were likely major contributors to organic-rich particles with low to mid-range aerodynamic diameter (dva). The similar temporal profiles and mass spectral features of the organic clusters and the factors from a positive matrix factorization (PMF) analysis of the ensemble aerosol dataset validate the conventional interpretation of the PMF results

The impact of due process and disruptions on emergency medicine education in the United States

INTRODUCTION: Academic Emergency Medicine (EM) departments are not immune to natural disasters, economic or political forces that disrupt a training program\u27s operations and educational mission. Due process concerns are closely intertwined with the challenges that program disruption brings. Due process is a protection whereby an individual will not lose rights without access to a fair procedural process. Effects of natural disasters similarly create disruptions in the physical structure of training programs that at times have led to the displacement of faculty and trainees. Variation exists in the implementation of transitions amongst training sites across the country, and its impact on residency programs, faculty, residents and medical students. METHODS: We reviewed the available literature regarding due process in emergency medicine. We also reviewed recent examples of training programs that underwent disruptions. We used this data to create a set of best practices regarding the handling of disruptions and due process in academic EM. RESULTS: Despite recommendations from organized medicine, there is currently no standard to protect due process rights for faculty in emergency medicine training programs. Especially at times of disruption, the due process rights of the faculty become relevant, as the multiple parties involved in a transition work together to protect the best interests of the faculty, program, residents and students. Amongst training sites across the country, there exist variations in the scope and impact of due process on residency programs, faculty, residents and medical students. CONCLUSION: We report on the current climate of due process for training programs, individual faculty, residents and medical students that may be affected by disruptions in management. We outline recommendations that hospitals, training programs, institutions and academic societies can implement to enhance due process and ensure the educational mission of a residency program is given due consideration during times of transition

A case of solitary kidney with duplex collecting systems and renal vascular variants in an adult male cadaver

We describe a unique solitary kidney with duplex collecting system and vascular variation observed in an 86-year-old White male formaldehyde- and phenol-fixed cadaver during routine academic dissection. The left renal fossa was empty with an intact adrenal gland, and the right renal fossa contained a fused renal mass with apparent polarity between the superior and inferior regions and two renal pelves converging into a single ureter. There were three right renal arteries supplying the renal mass; the superior and middle arteries were noted to be postcaval and the inferior artery was precaval. There were also two right renal veins draining into the inferior vena cava and following a regional distribution with the superior vein draining the inferior portion of the renal mass. Despite generally being asymptomatic, the detection of renal anatomical variants is clinically important for appropriate patient management and surgical interventions

Effects of sedentary behaviour interventions on biomarkers of cardiometabolic risk in adults: systematic review with meta-analyses.

CONTEXT/PURPOSE: Observational and acute laboratory intervention research has shown that excessive sedentary time is associated adversely with cardiometabolic biomarkers. This systematic review with meta-analyses synthesises results from free living interventions targeting reductions in sedentary behaviour alone or combined with increases in physical activity. METHODS: Six electronic databases were searched up to August 2019 for sedentary behaviour interventions in adults lasting for ≥7 days publishing cardiometabolic biomarker outcomes covering body anthropometry, blood pressure, glucose and lipid metabolism, and inflammation (54 studies). The pooled effectiveness of intervention net of control on 15 biomarker outcomes was evaluated using random effects meta-analyses in the studies with control groups not providing other relevant interventions (33 studies; 6-25 interventions analysed). RESULTS: Interventions between 2 weeks and 0.05) were also small, and beneficial in direction except for fat-free mass (≈ 0.0 kg). Heterogeneity ranged widely (I2=0.0-72.9). CONCLUSIONS: Our review of interventions targeting sedentary behaviour reductions alone, or combined with increases in physical activity, found evidence of effectiveness for improving some cardiometabolic risk biomarkers to a small degree. There was insufficient evidence to evaluate inflammation or vascular function. Key limitations to the underlying evidence base include a paucity of high-quality studies, interventions lasting for ≥12 months, sensitive biomarkers and clinical study populations (eg, type 2 diabetes).

Development of a process to disclose amyloid imaging results to cognitively normal older adult research participants

Introduction: The objective of this study was to develop a process to maximize the safety and effectiveness of disclosing Positron Emission Tomography (PET) amyloid imaging results to cognitively normal older adults participating in Alzheimer’s disease secondary prevention studies such as the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) Study. Methods: Using a modified Delphi Method to develop consensus on best practices, we gathered and analyzed data over three rounds from experts in two relevant fields: informed consent for genetic testing or human amyloid imaging. Results: Experts reached consensus on (1) text for a brochure that describes amyloid imaging to a person who is considering whether to undergo such imaging in the context of a clinical trial, and (2) a process for amyloid PET result disclosure within such trials. Recommendations included: During consent, potential participants should complete an educational session, where they receive verbal and written information covering what is known and unknown about amyloid imaging, including possible results and their meaning, implications of results for risk of future cognitive decline, and information about Alzheimer’s and risk factors. Participants should be screened for anxiety and depression to determine suitability to receive amyloid imaging information. The person conducting the sessions should check comprehension and be skilled in communication and recognizing distress. Imaging should occur on a separate day from consent, and disclosure on a separate day from imaging. Disclosure should occur in person, with time for questions. At disclosure, investigators should assess mood and willingness to receive results, and provide a written results report. Telephone follow-up within a few days should assess the impact of disclosure, and periodic scheduled assessments of depression and anxiety, with additional monitoring and follow-up for participants showing distress, should be performed. Conclusions: We developed a document for use with potential study participants to describe the process of amyloid imaging and the implications of amyloid imaging results; and a disclosure process with attention to ongoing monitoring of both mood and safety to receive this information. This document and process will be used in the A4 Study and can be adapted for other research settings
